      Pull iommu fixes from Joerg Roedel:
      
       - Fix a use-after-free of the device iommu-group. Found in the arm-smmu
         driver, but the fix is in generic code.
      
       - Fix for the new Allwinner IOMMU driver to use the atomic
         readl_timeout() variant in IO/TLB flushing code.
      
       - A couple of cleanups to fix various compile warnings.

      mm: document warning in move_normal_pmd() and make it warn only once · f81fdd0c
      Linus Torvalds authored
      Naresh Kamboju reported that the LTP tests can cause warnings on i386
      going back all the way to v5.0, and bisected it to commit 2c91bd4a
      ("mm: speed up mremap by 20x on large regions").
      
      The warning in move_normal_pmd() is actually mostly correct, but we have
      a very unusual special case at process creation time, when we may move
      the stack down with an overlapping mode (kind of like a "memmove()"
      except using the page tables).
      
      And when you have just the right condition of "move a large initial
      stack by the right alignment in the end, but with the early part of the
      move being only page-aligned", we'll be in a situation where we're
      trying to move a normal PMD entry on top of an already existing - but
      now empty - PMD entry.
      
      The warning is still worth having, in case it ever triggers other cases,
      and perhaps as a reminder that we could do the stack move case more
      efficiently (although it's clearly rare enough that it probably doesn't
      matter).
      
      But make it do WARN_ON_ONCE(), so that you can't flood the logs with it.
      
      And add a *big* comment above it to explain and remind us what's going
      on, because it took some figuring out to see how this could trigger.
      Kudos to Joel Fernandes for debugging this.
